Force Z and the meaning of 'no air support'

Brewster Buffalo fighters at Singapore are described as waiting for a Royal Navy request while the ships believed air support was unavailable. The explanation given is a mismatch between service procedures. The RAF message concerned the absence of strike aircraft under the older agreement, while Royal Navy experience in the Mediterranean had established a distinction between fighter support and strike support. Ships arriving with Admiral Phillips used those updated procedures, but the Far East organizations had not adopted them. A general statement about unavailable air support could therefore be understood differently by the sender and recipient. In the counterfactual, air-defense radio traffic or a timely request could bring Buffalo fighters against the unescorted Japanese bombers.
